Testosterone – what do your numbers mean?
Have you had your testosterone level measured and are unsure what the numbers mean? Here's a clear explanation of the normal range, what a high or low level might mean, and when it makes sense to get tested.
What is the normal range for Testosterone?
What is the normal range for Testosterone?
The normal range for testosterone varies depending on age, gender, and the laboratory's analysis methods. For men, total testosterone levels typically range between 11-34 nmol/L for the 20-30 age group, gradually declining with age to 8.4-31 nmol/L for men over 80. For women, levels are significantly lower, with a normal range of below 2.4 nmol/L for women over 20. It's important to note that reference intervals can vary slightly between laboratories. Testosterone levels close to the borderline values may indicate a need for further investigation, especially if symptoms such as fatigue, decreased libido, or muscle loss are present.
What does a low level mean?
A low testosterone level can lead to a range of symptoms, including decreased sexual desire, erectile dysfunction, fatigue, depression, loss of muscle mass, and increased fat mass. In men, it can be caused by conditions such as hypogonadism, chronic diseases, obesity, or certain medications. Women with low testosterone may experience decreased libido and energy levels. Particularly vulnerable groups include older men, individuals with chronic diseases, and those taking medications that affect hormone production. If low testosterone is suspected, a doctor should be consulted for a thorough evaluation and potential treatment.
What does a high level mean?
An elevated testosterone level in men can lead to symptoms such as increased aggression, acne, and in some cases, infertility due to inhibition of the body's own production. In women, it can cause masculinization, including increased body hair, a deeper voice, and menstrual irregularities. Causes of high testosterone can include androgen-producing tumors, polycystic ovary syndrome (PCOS) in women, or doping with anabolic steroids. It is important to seek medical attention if abnormally high levels are suspected to identify and treat the underlying cause.
